Barnyardgrass (Echinochloa crus-galli [L.] Beauv.), a troublesome weed in rice production, has been confirmed for the first time to be resistant both chloroacetamide (butachlor)- and acetanilide (propanil)-group herbicides commonly used direct-seeded Philippines. Resistance screening showed that 17 of 18 sampled populations (94%) were butachlor + propanil. Dose–response assays using propanil on resulted all but one not being controlled at twice recommended rate field application (1.4 kg ai...
Southeast Asia’s rich natural resources and favorable climatic conditions make it conducive for intensive rice-based, corn-based perennial crops-based cropping systems. Regardless of the system, weeds remain to be among major factors that limit yields. The use herbicides manage in these systems has been increasing through years. 2,4-D started late 1940s remains as a herbicide control rice weeds. 1980s saw introduction multiple [...]
International agricultural research centres use approaches which aim to create effective linkages between the practices of farmers, introduced technologies and wider environment that affects farming. This paper argues such new require a different type monitoring as complement conventional tend favour quantitative assessment adoption impact at farm level. In this context, we examined data from an Adaptive Research (AR) project highlighting complementary qualitative analysis. Our emphasis is...
Implementing a cropping intensity program with rice cultivation four times year (CI 400) can be achieved using early maturing varieties of rice. However, this development needs to pay attention the adaptability planted ensure successful implementation. The approach is combination assessing stability and productivity potential. This concept has been developed applied in several studies, including research on considered less comprehensive because it non-parametric only focuses one analysis....
The genotype evaluation process requires analysis of GxE interactions to ascertain the responsiveness a various environments, including development early maturing rice. However, concept interaction is relatively specific grain yield. In contrast, yield highly polygenic, so assessment should be carried out with multivariate approaches. Therefore, in evaluating developed, especially for rice genotypes. study aimed develop comprehensive approach improve comprehensiveness and analysis. was...
